ZITN HQA-J1TR Quartz Flexure Accelerometer and HQA-JM Miniature Quartz Flexure Accelerometer are both single-axis, force-balance accelerometers. The Quartz Flexure Accelerometer captures external acceleration signals based on the proof mass detection principle. Through built-in servo circuit demodulation, amplification, and processing, it outputs a current signal proportional to the acceleration. The HQA-J1TR Quartz Flexure Accelerometer offers optional temperature sensor integration: Pt1000; 18B20; AD590; or none.
Application
High-precision navigation systems for aviation and aerospace.
Product Features
Wide input voltage range, low power consumption.
High precision and high stability.
